As we can see from the diagram, the garden consists of a circle, with radius AC=r=10 feet long.

1.
The area of the circular garden is the area of the circle, with radius r=10 feet.
Area = π r^2 = π 10^2 = 3.14*100 = 314 sq. ft.

2.
Length of fencing equals the circumference of the garden
= 2 π r = 2 (3.14) 10 = 62.8 feet.
